How do animals get energy from food?

Question

A.
Electrical impulses in the body are used to change food into energy.
B.
Molecules from the food react with oxygen and release energy.
C.
Sound vibrations in the body are used to change food into energy.
D.
Molecules from the food react with carbon dioxide and release energy

Answer 1

The correct answer is: B. Molecules from the food react with oxygen and release energy.

In animals, the process of converting food into energy primarily occurs through cellular respiration, where glucose and other molecules from food react with oxygen to produce energy in the form of ATP (adenosine triphosphate).
